Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571324, here are decompositions:

67 + 31571257 = 31571324
157 + 31571167 = 31571324
181 + 31571143 = 31571324
241 + 31571083 = 31571324
277 + 31571047 = 31571324
307 + 31571017 = 31571324
331 + 31570993 = 31571324
457 + 31570867 = 31571324

Showing the first eight; more decompositions exist.
